Congrats on your sobriety!!! Keep it up girl!
I understand about the drinking and smoking affecting TTC'ing. Both of his vices don't help with his little swimmers. If you google about it and print off some research, maybe you can sit down and talk to him about it. While he is cutting back he can help add to his motility. I hear grapes and walnuts can help a lot. Omega 3s & 6s. MH said all of that, not sure if it's true or not. He is also a drinker. We seem to drink together on my two (ish) weeks before O but he always takes it to the next level. And I feel like view of the matter is skewed too because my dad, brother and both grandfathers were/are alcoholics. Since TTC we have discussed it and he tries to minimize the drinking during the week and keeps it to the weekend. I think having conversation would help a lot.
Now for the smoking... He should just quit now. He can't be holding the baby after smoking a cigarette, never mind TTC. Third hand smoke is just as terrible. He needs to quit for sure. Help him, support him, but be firm. He needs to quit.
Good luck. Let us know how the conversation went when it happens.
